The Perseus Cluster of Galaxies
Explanation:
Here is
one of the
largest objects
that anyone will
ever see on the sky.
Each of these fuzzy blobs is a galaxy, together making up the
Perseus Cluster
, one of the closest
clusters
of galaxies
.
The cluster is seen through a foreground of faint stars in our own
Milky Way Galaxy
.
Near the cluster center, roughly 250 million light-years
away, is the cluster's dominant galaxy NGC 1275,
seen
here
just left of picture center.
A prodigious source of
x-rays
and radio emission,
NGC 1275 accretes
matter as gas and galaxies fall into it.
The
Perseus Cluster of Galaxies
is part of the
Pisces-Perseus supercluster
spanning over 15 degrees and containing over 1,000 galaxies.
At the distance of NGC 1275, this view covers about 1.5 million
light-years.
